The problem is that the burden increases as the burden increases. On the other hand, even in the device shown in JP-A No. 61-11614, when the necessary screen is displayed at the beginning, it is possible to efficiently obtain subsequent detailed data, etc.; The same problem as in the former case arises as to which screen to select. In addition, in conventional systems, the screen display related to one piece of data is targeted, so when there is multiple data of interest, the number of inputs of instructions with a pointing device increases, making the single screen selection process complicated. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a process monitoring device that allows an operator to easily select a screen that he or she wants to display with a simple operation.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses process data, alarm information generated in the plant, and human speech information as input, and uses alarm setting values and physical information related to the process data as input.

The display control section 6 selects a screen and displays it on the display device N7 based on the knowledge stored in the database 93 for determining the display order timing, display method, etc. of the plurality of screens selected by the screen selection section 5. do. The input device 8 performs input for changing the display. The detailed operation of each part will be explained below.

2 and 3 are examples of knowledge stored in the database 91 for use by the data extraction unit 4. FIG. Second
The diagram summarizes knowledge about process data, including data names, 9 normal value ranges, alarm setting values and alarm names, names of other data that have physical dependencies and influence relationships, and related systems and It consists of the device name, etc. Further, FIG. 3 summarizes knowledge regarding driving operation items, and is composed of operation names, conditions for operation, data to be noted during operation, operation items to be performed next, etc. Note that both Figures 2 and 3 show examples, and this knowledge will be used in the explanation of the processing below, but in general, the constituent elements of knowledge are not limited to the elements in the figures. You can add it if necessary.

4 to 6 are flowcharts showing an outline of the processing in the data extraction section 4. FIG. FIG. 4 shows data extraction processing based on alarm information, and in step 100, process data indicating an abnormal value that is the cause of the alarm being generated is searched for. This is to search for the process data that causes the alarm by referring to the knowledge shown in FIG. In step 101, process data that has a physical dependency relationship or influence ripple relationship with the searched process data is searched for.

This is done by searching for relevant data in the knowledge of FIG.

FIG. 5 shows data extraction processing based on process data values. In step 102, the normal value range information in the knowledge shown in FIG. 2 is checked to see if the process data values deviate from normal values. Check it out. In step 103,
If the value deviates from the normal value range, search for related data regarding the process data.

FIG. 6 shows data extraction processing based on the operator's utterance information. In step 104, keywords such as process data names, equipment names, operation item names, etc. included in the operator's utterance information are separated. Step 106 is executed when the keyword information is a process data name, and similarly to step 103 in FIG. 3, data related to the process data is searched for. Step 107 is executed when the keyword information is a device name, and searches for process data that includes the device in the keyword information as related device information in the knowledge of FIG. Step 108 is executed when the keyword information is an operation item name, and refers to the knowledge shown in FIG. 3 to search for process data to be considered during operation.

FIG. 7 is an example of knowledge stored in the database 92 for use in the one-screen selection section 5, and is SO1! related to the structure and contents of the display screen. It is. That is, it consists of a screen name given to each screen, a related system name, a process data name, a number identifying the nine screens, and information representing the contents of the nine screens.

FIG. 8 is a flowchart showing an outline of the processing in the screen selection section 5. In step 110, it is checked whether information regarding the process data extracted by the data extraction section 4 is included in each screen. This corresponds to steps 101, 103, 106, 107, and 108 in Figures 4 to 6.
This is done by checking whether the process data name searched for is included in the knowledge shown in FIG. In step 111, a screen containing one or more pieces of information regarding the process data extracted by the data extraction unit 4 is extracted.

FIG. 9 is a flowchart showing an outline of the processing in the display control unit 7. In step 120, the priority for displaying the plurality of screens extracted in step 111 is determined, and 5 screens are displayed. In this example, information regarding process data extracted by the data extraction unit 4.

A criterion is used in which the screen has a higher priority as the number of screens increases. Such judgment criteria are stored in the database 93 and are used as necessary. Note that the value of the number i of screens to be displayed can be arbitrarily set in consideration of the size of one display device. In step 121, the screen selection signal inputted by the operator from the input device 8 is analyzed to recognize the screen that the operator wants to focus on. The input method may be a method of inputting the screen number from a keyboard or a method of pointing to the screen displayed in step 120 using a pointing device. In step 122, step 121
Enlarge and display the screen recognized by .

FIG. 10 shows an example of the screen display of the display device 7, in which the screens containing the process data extracted by the data extracting means 4 are arranged in the order of windows 51 containing the most data.
1 to 514 are displayed. This is Figure 9 Step 12
Displayed with 0 processing. When the operator points to the window 511 using the input device 8 (for example, a pointing device), the screen there is enlarged and displayed as the screen 52 (step 122). It is also possible to display any screen by inputting the screen number. Note that the window screens 511 to 514 can be omitted and displayed to the extent that the screen contents can be understood.

According to this embodiment, alarm information and process data.

Screens that require the operator's attention and multiple screens that are expected to attract the operator's attention can be automatically displayed simultaneously based on the operator's utterance information, making it easier for the operator to monitor the process and make screen selection easier. The burden on the operator can be significantly reduced.

Next, FIG. 11 and FIG. 12 show an embodiment in which the screen selected by the screen selection section 5 is displayed in a method different from the above-described embodiment. FIG. 11 shows windows 511 to 51.
The types of screens to be displayed in 4 are set in advance, and each window is controlled to display a screen with a high priority. This is because the amount of information contained on the screen may differ depending on the type of screen, so step 1 in Figure 9
Since it is expected that certain types of screens will be more likely to be selected based on the 20 criteria, we have solved these problems and made it possible to view various types of screens.

Furthermore, in FIG. 12, three screens with high priority among the screens selected by screen selection section 5 are displayed in windows 511 to 513, and another window 514 displays screens with low priority that were not displayed. do. The information displayed on the window 514 includes, for example, the screen number and screen contents. This makes it easy for the operator to select a screen that includes information of interest. In particular, even if the operator forgets the screen number, by looking at the window 514, the necessary screen can be selected and displayed.

Furthermore, in the above-described embodiment, the screen selected by the one-screen selection unit 5 is displayed with a higher priority as the screen contains more data extracted by the data extraction means 4 (see FIG. 9). In step 120), an example will be described in which this priority is determined by another method that takes into account past history. In this method, when the total number of process data extracted by the extraction means 4 is n, and the number of data included in a certain screen is m, the data content rate of that screen is m/n.
It is. In the above example, this value was used as it is as the priority, but in this example, the above content rate is used as the initial value of the priority, and after displaying multiple times, the previous data content rate and the data content at that time are The sum of the rates is used as the priority at that time. FIG. 13 shows the selection of display screens in chronological order when the display method of this embodiment is used, and the display time is t.
As time passes from 1 to t6, the data content of screens A to F at each time is indicated by a decimal in the table.

At the bottom, four of the screens A to F selected by the method of this embodiment at each display time are shown.
For example, at time t1, the data content rate is set as the priority as the initial value, and screens A-D with the larger value are selected, and at time t2, the screens A-D are selected in descending order of the sum of the data content rates at times t1 and t2. is displayed as selection 1. However, at time t4, for example, screen A with the smallest data content rate at that time is selected and displayed, but this is not the case at time t3. The sum of the data content rates at t4 is screen C,
This is because it is larger than that of screen D (which has a higher content rate than screen A when looking only at time t4).

It should be noted that this embodiment may be further generalized, and the priority may be obtained by multiplying the priority value of each time displayed in the past by a weighting coefficient and adding the resultant product. With this method, a screen with a continuously high priority is displayed with priority over a screen with a temporarily high priority, and it is possible to appropriately support the operator's process monitoring.

Further, as another criterion for determining the priority of the screen, the degree of deviation of the value of the process data from the normal value may be considered. This means that if there is process data that significantly deviates from normal values, operators should make a judgment to monitor the process data, and screens that contain information for that purpose should be displayed preferentially. . Also,
The priority may be determined in consideration of information about the location where the display device is installed. The process monitoring operation panel is the object of operation,
It may be divided into multiple parts for ease of use. In that case, monitor and operate each operation panel 1. It is effective to select and display important screens.

Note that the timing of screen selection and display (time t i -t, 6 in FIG. 13) is at a preset time interval,
When an alarm occurs, when process data deviates from the normal value range, when a keyword is recognized from operator utterance information, when an operator performs some operation, or when an operator issues a screen switching request. It may be set as the point in time.

Also, the display device was 】-, but this is the first one. It is also possible to use two. In this case, the display H of ]- machine displays only both sides of the compound V selected by the screen selection section 5, and the display of the other machine displays the input screen selected by the operator using input and W8. Display the screen, that is, window 5 in Figure 10
The portions 11 to 514 and the screen 52 are displayed on separate display devices. With this configuration, a large number of screens selected by the screen selection section 5 can be displayed, making it easier for the operator to select a screen.

[Effects of invention According to the invention, plant data, alarm information.

Based on the operator's utterance information, multiple screens containing valuable and important information for process monitoring can be displayed at that time, and screens can be selected with a -degree operation, and the screen selected by the operator is displayed in a larger size. This allows operators to support process monitoring. Furthermore, by displaying the screen numbers and contents of screens that include noteworthy information or information that is considered to be of interest, there is an effect that screen selection by Driving X becomes easier.
